Vitality score
Vitality score 36.5/100 — Few services (model fr-v0.2).
Confidence: medium (sources disagree on Restaurant).
Better served than 7 % of the 5,561 communes of a similar size.
Compare this with communes of a similar size. The score measures how well a place is served relative to its own size band, and larger communes score higher as a rule — so it reads meaningfully against another village, and misleadingly against a town.
Measured but not scored in this model: Market. See the methodology for why.

Climate
Where this sits nationally
An average of 16 days a year at or above 30 °C and 52 days at or below 0 °C, over 19 complete years in 1995–2024. [10]
Measured at the FLINS-SUR-SEINE weather station, 6.6 km away at 32 m; the village itself is at 72 m. [10]
Muggy days — a dew point at or above 18 °C — average 1 day a summer. [10]
Humidity measured at MAGNANVILLE, 9.1 km away at 123 m, over 30 summers. [10]
That station sits 51 m above the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. [10]
An average of 721 mm of rain a year, spread over 123 days — about 5.9 mm on a day it rains. [10]
Rainfall measured at LAINVILLE, 6.5 km away at 150 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. [10]
What property sold for
203 houses sold between 2021 and 2025, at a median of 263,700 € — 2,835 € per m² of built surface. [11]
31 flats sold over the same window, at a median of 122,000 € — 2,429 € per m². [11]
The median across Yvelines is 3,657 € per m², so this commune sits below it. [11]
These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.

…and in much the same climate
The same match on size and services, narrowed to communes whose summers, winters and summer humidity are all close to Issou's. All three are required, so this section is absent for the 11.8 % of communes with no humidity station near enough to measure: two temperature axes alone cannot tell a muggy coast from a dry one.
